SPECIFICATION forming part of Letters Patent N0. 788,519, dated May 2, 1905. Application filed May 13, 1904. Serial No. 207,811.

To all whmn it may concern:

Be it known that I, CHARLES A. COFFIN, a citizen of the United States, residing at Cedarfalls, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Seals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to self-sealing seals for car-doors; and it consists in the novel construction and combination of the parts hereina'fter fully described and claimed.

In the drawings, Figure 1 is a plan view of the seal. Fig. 2 is a side view of the seal, showing the sealing-pocket in section. Fig. 3 is a similar side view, but shows the parts disconnected.

A is a flexible metallic stri which is bent to the form of a loop. This ooped strip, as shown, has a hook I) at one end and a hook c at the other end, which is arranged inside the jaw of the hook I) and provided with an outwardly-bent tip 0, which is outside the tip of the hook I).

D is the sealing-pocket, which is formed of metal and provided with a slot (2 in its back portion. This slot extends across the pocket and divides its back into two parts 0 and f,

which are bent out of'line with each other at the edges of the said slot. The part c, which is bent outward, is longer thanthe part f, which is bent inward. V

The hook I) is inserted through the slot first and then the hook c. As soon as the tip 0 of the hook c has passed through the slot it springs out to the position shown in Fig. 2, so that the hook c engages with the part f when drawn back a little and so that it is impossible for either or both of the hooks to be withdrawn through the slot without destroying the sealing-pocket.

What I claim is The combination, with a sealing-pocket provided with a slot which divides its back into two parts 6 and f, said partebeing longer than the part f and arranged at an angle to the front face of the said pocket and projecting rearwardly beyond the plane of the said part f; of a flexible shackle provided with hooks which engage with each other and with the said partf when thrust through the said s 0t.

In testimony whereof I have aflixed my signature in the presence of two witnesses.

CHARLES A. COFFIN.
